Class: Gherkin::TokenScanner
- Defined in:
- lib/rubypitaya/app-template/vendor/bundle/ruby/3.1.0/gems/cucumber-gherkin-23.0.1/lib/gherkin/token_scanner.rb
Overview
The scanner reads a gherkin doc (typically read from a .feature file) and creates a token for line. The tokens are passed to the parser, which outputs an AST (Abstract Syntax Tree).
If the scanner sees a # language header, it will reconfigure itself dynamically to look for Gherkin keywords for the associated language. The keywords are defined in gherkin-languages.json.
